![**Problem Description:**
You tossed out a ball from a building at a height of 50.0 meters above the ground with an initial velocity of 9.00 m/s and an angle of 25° to the horizontal. It strikes the ground after 5.00 seconds. With the positive x-direction chosen to be out of the window, how far horizontally from the base of the building does the ball strike the ground?
**Solution Approach:**
To find the horizontal distance from the base of the building where the ball strikes the ground, we need to analyze the projectile motion of the ball:
1. **Initial Velocity Components:**
- Horizontal component (vx): \( v_0 \cdot \cos(\theta) \)
- Vertical component (vy): \( v_0 \cdot \sin(\theta) \)
Where \( v_0 = 9.00 \, \text{m/s} \) and \( \theta = 25^\circ \).
2. **Horizontal Distance Calculation:**
- The horizontal distance (x) can be calculated using the formula:
\[
x = v_x \cdot t
\]
- Since there is no acceleration in the horizontal direction, the horizontal component of velocity remains constant.
3. **Substituting the Values:**
- Calculate \( v_x = 9.00 \cdot \cos(25^\circ) \)
- The time of flight (t) is given as 5.00 seconds.
4. **Final Calculation:**
- Substitute these values into the equation for x to find the horizontal distance.
This approach gives a step-by-step explanation of how to solve the problem of determining the horizontal range of the projectile.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5f38070e-ad45-48a5-82b1-6e1ca7cd9dbf%2F95a3e211-6d6c-4de3-8bc4-4e757b973a1c%2Foja4zua_processed.png&w=3840&q=75)
